WIRE-WINDING MACHINE.

To all whom z'tmay concern:

Be it known that I, EMORY GLENN SIMP- SON, a citizen of the UnitedStates, residing at Detroit, in the county of Wayne, have invented a newand useful Improvement in Wire-Winding Machines, of which the followingis a specification.

.This invention relates to machines for winding wire about loops, and isespecially intended for winding the ends of a loop in a stay wire foraeroplanes. The features of construction and the novel parts will appearin the more detailed de-. scription following.

In the drawings,

, Figure 1 is a longitudinal section of the machine partly in elevation.

' Fig. 2 is a plan view.

Fig.- 3 is a cross section on the line CC of Fig. 1.

Fig; 4 is a cross'section of the loop-holder in closed position.

Fig. 5 shows the same part in open posi-. tion.

The frame of'the machine is designated a adapted to take the sleeve 0which is secured in position bythe set screw d. This sleeve performs thedouble function of acting as and has a head 6 provided with an opening abearingshaft and a socket for the removable loop-holder e. Theloop-holder e is a split cylindrical member whose construction will bebetter understood by referring to Figs. 4 and 5. This comprises twoparts of a cylinder hinged together by the knuckles f and the knuckle pmg. At

the center of the cylinder the two-part cylinders do not quite'meet by aspace suflicient' to hold the two ends of a wire loop. The consequenceis that when the cylindrical holder is opened up, as shown in Fig. 5,the wire looped back upon itself may be inserted by laying: it in theopened cylinder. The cylinder may be closed up as shown in Fig. 4,leaving the loop portion of the wire exposed as shown in Fig.1 at theendof the cylinder. Pressure pins it operated by coil springs serve toafford a friction on the loopedends of the wire so as to hold the samefrictionally. Obviously when the twopart cylinder is inserted in thesocket formed by the sleeve 0, this serves to hold the'two partstogether.

On the outside of the sleeve 0 is journaled Specification of LettersPatent.

pulley n and connected with this pulley by means of the clutch 0.

This rotating head carries a-spool-holding stud 7) upon which is adaptedto be rotatably mounted the spool of wire. q. A tension deviceis locatedon the head opposite the spool-holding stud and comprises simplyasegmental block 1" with a circumferential around which and in whichlies the wire to be fed on to the work. The pivoted bar 25 has a foot 10adapted to press against the wire that lies in the circum- 1 ferentialgroove. This foot 'u, is urged against the .wire'by means of thetractile spring '0 whose tension may be adjusted by turning the screw rmso as to lengthen or shorten the spring. Obviously by lengthening thespring the pressure on the wire is greater and consequently the tensiongreater between the tension block and the loop or work.

When the machine is set into operation by shifting the clutch lever ,w,the wire spool and tension device are caused to rotate about thestationary loop-container and consequently winds the wire uponthe loop,but this winding would be a mere piling up were it not for the fact thatthe work is advanced just the proper distance continuously to make thewind a true and tight spiral. This advance of the work is secured byconnecting the power shaft and threaded shaft 3 by means of a properlycalculated reduction gearingz. A- slide 1 traveling longitudinally ofthe machine ina. slide-way has a liftable half nut connection 2 with thethreaded shaft; hence the slide being constrained from rotation and thethreaded shaft engaging with the nut, rotation of the shaft causes theslide to travel away from the stationary head I) of the machine. A hook3 is carried by the top of the slide and is adapted to be hooked intothe looped work. Consequently when the rotating head begins to rotatethe work simultaneously begins to travel away from the stationaryhead atjust the right pace to form a true but tight spiral.

The stem 4 rises from the half nut 2 and the nut may belifted 0E fromthe threads of the shaft 3/ 'by means of the lever 5.. The

compression spring 6, however, normally tends to keep the half nut inengagement with the threads.

By the-machine here described, loop ends may be bound together and theirwindings machine laid, as distinguished from what has been the practiceheretofore to wind these by hand. The prior practice-has been hard, slowand less satisfactory work than is performed by this machine.
